I would say it's too small, but if you can fit two hides in there for him as a hot side and a cold side, it would be okay as a temporary cage. He seems to be still fairly small, judging by the cage, I would suggest maybe a 15 or 20 gallon long tank, if your preference is tanks. If not, then a 28- 32 quart tube would work just as well, make sure they have locking lids and drill or solder holes into the tube, just be careful not to crack the tube if you're drilling. If you have any other questions I would be happy to help. Good luck, he's real nice.
